T. J. BURKE UNIVERSAL PIPE JOINT Filed Jan. 18. 1924 2 Sheets-Sheet l T. J. BURKE UNIVERSAL PIPE JOINT Filed n- 18, 1924 2 Sheets-Sheet 2 taceot the flange J'l' oi the section set it of the head of the section 2 is provided with a circumferential flange 1 7 which projects from the planeof the seating face 16 and surrounds the sai face as well as periphery of the flange 7, the depth of the flange ll? heing substantially equal to the thickness of the flange 7. A. cap ring 18 is secured by stud bolts 19 or bolts and nuts, if preferred, to the ofiset 14: or the head 12 otfthe section 2, the said holts being fitted through ears or lugs 20 formed upon the pe ripheries oi the otiset and'the cap ring, as clearly shown in Figures l '3 of the drawings. The outer periphery of the cap ring 18 is in registration with the outer circumterential surface of the flange ll, but the cap ring is of a width, at any oint in its circumference, greater than the richness cat the flange it, so that the inner peripheral portion oi the cap ring overlies the flange it oftho head 63 oi the section '1; the manner host shown in Figure 2 of the drawings and serves to hold the heads together in their properly assembled relation, it heing understood, of course, that the heads may have tree relative swiveling movement. By reif erence to Figure 2015 the drawings, it will he observed that the walls 10 and i5, and the portions oi the faces 9 and t3 which the space between these walls, define an annular chamber 21 to accommodate a packing element which is indicated by the numeral The packing element 22 is initialiy in flit ' the term of a flat leather ring, as shown. in

Figure 4 of the drawings, and the time of assembling" the parts the ring; is folded on a circular line midway between its inner and outer peripheries, thereby providing a con meeting portion 23 and side flaps T llie tendency, of course, is for the side flaps ot the ring to spread apart and they therefore, snugly bear against the wall. surfaces to and 15 when. the parts are assembled, The ring is so proportioned as regards its dimensions and as regards the dimensions at the walls 10 and 15, that when folded or doubled to the required. form, the outer surface of the connecting portion 23 the ring will contact the seating tace it where this face spans the space between the walls 10 and lo, and the edges of the flaps wiilenugly contact the seating face 9 where it spans the spacehetween said walls 10 and 15.

It will now be evident that while the sec tions 1 and 2 may have relative swiveling movement with perfect freedom, preferably the heads 6 and 12 are reinforced enterioriy by fins 25 and in this manner it is possible to form the heads of smaller external diame ter than would otherwise be practicable so that the joint is not bulky as compared with the diameter of the pipes which it is to con n'ect.

The se tion 2 is provided at its end oppo site at which the head 12 is located, with an offset circumferential flange indicated the numeral 26, which is exteriorly preferably of substantially rectangular form as shown in fdigure 3 of the drawings, the in nor surface of the flange, however, being of cylindrical contour, and constituting a wall indicated hy the numeral 27. The section 3 is adapted to he fitted rotatably within the flange 26 is provided with a circumferential flange 28 spaced inwardly from its said end of a diameter to rotatably and. snugly fit within the recess defined by the said wali, 2'], The end of the section 3 abuts the end the body 11 of the section 2, as clearly shown in Figure 2 of the drawings, and which end of the section presents a seat-- ing face indicated by the numeral 29. it will, now be evident that the inner surface 2? of the 26, the seating face 29 of the body ll of the section 2, the taco of the flange 28 which opposes said seating'i ace and the exterior surface of the body of the section 3 define an annular chamber 30 to accommodate a p cking element which is indicated by the mun l 31 The packing elenient 31 is identical construction with the ele ment 22 orevicusly described,

By re will he s dent that any fluid under pressure which might hy any possibility pass be tween the seating; i'aces 9 and 13 oi the sec tions 1' and 2, or seating face and abut ting en s the sections 2 and 3, would, if undersuticient pressure, enter the recess in the paclzine; eieinents 23 and 31 respectively and tend, anything, to further spread the ilaps oi said elements and more firmly bind the i ,itlllSiJ the walls of the packing housing..-, escape it will be evident, there fore, that the peeling elements as arranged hi 2, are intended to he employed where a aid under pressure is to he hassed through joint. 'Where the joint is int-er posed in suction line, however, he aching will he reversed in order to reta n the sections 2 and 8 in their assembled relation, a cap ring corresponding to the ring 18 is secured by holts 33 to the ofi set fian e 26 oi the section 2 at its inner peripheral portion overhangs the flange 28 ot" the said section 3, and order to permit of attachment ofthe other pipe to the section 8, said section at its outer end is interiorly threaded as indicated hy the numeral 34.

Figure of the drawings illustrates modification oi the invention and more especiaily as regards the packing element. In this modified form, which is indicated by the numeral 35, const tutes split metallic ring closely resembhng the IW'EllrlLLHOWII piston ring, and where the ring employed as a packing element hot-ween the ence Figure 2 of the drawings,

J reby positively insuring against the packing element,

sections corresponding to the sections 2 and 3, and which sections in the said figure are indicated respectively by the numerals 36 and 37, the section 37 will be provided with spaced circumferential flanges 38 to provide a groove 39 to receive the said packing ring, the structure being otherwise substantially identical with that previously described. Of course, a ring such as the ring 35 may equally well be employed in the structure shown in Figure 2, and as a pack ing element between the sections 1 and 2, it being in such case, within the annular chamber 21 in lieu of the packing element 22.

It will be evident that the fins 25 serve not only, as previously stated, to reinforce the walls of the heads 6 and 12 but also serve to reinforce the flanges 7 and 14, thus permitting of these parts being made thinner and lighter than would otherwise be practicable.

While in the illustrated embodiment of the invention, the flange 7 and cap ring 18 and the flange 26 and cap ring 32 are con nected by bolts, these parts may be connect ed by screw threads in joints of smaller sizes.

It will be evident that in view of the fact that the interior of the head of each section is of the contour of a sector of a sphere, free and unobstructed flow of fluid or matter through the pipes and the joint connected thereby will be had regardless of the angle to which the joint sections are adjusted, as well as when the sections are in alinement. For example, if the sections are rotated to assume an angle of 90 with respect to each other, precisely the same character of pas-. sageway will be provided as in the instance of two ordinary pipes connected by an ordinar elbow.

aving'thus described the invention, what is claimed as new is: i

A pipe joint comprising sections assembled end to end, said sections each having its inner end formed with an annular edge disposed in a plane extending diagonally with respect to the axis of the section-and adapted for face to face contact with the annular edge of the other section, a collar extending circumferentially about one section in a plane spaced from and parallel to the end 1 thereof to provide the section with an extended end portion, an annular flange carried by the other section and having face to face contact with the collar of the first-mentioned section, said flange being of-greater dimensions than said collar and having its inner peripheral edge face spaced from the outer peripheral face of the extended end portion of the first-mentioned section to deme an annular packing receiving pocket between the sections, acking in said pocket, an upstanding annu ar wall carried by said flange and surrounding said wall and overlapping said collar, and removable means carried by said collar to retain the sections joined and permit turning of one with respect to the other.

In testimony whereof I aflix my signature.
